A rare case of severe tricuspid regurgitation caused by TIPS stent migrating into the right atrium

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) is a common, effective and reliable treatment modality for portal hypertension. Migration of the TIPS stent into the right atrium is a rare and fatal complication. CASE PRESENTATION: We report a case of severe tricuspid regurgitation caused by a stent migrating into the right atrium in a patient hospitalized with refractory ascites due to cirrhosis. DISCUSSION: In this case, it is noteworthy that secondary stenting, which is necessary especially in cases of occlusion, significantly increases the risk of migration. CONCLUSION: Although a rare complication, intracardiac stent migration should be considered in patients with a history of TIPS in the presence of a new heart murmur and signs of arrhythmia.
